Two-digit LED display and control knob with push-
button, which set PULSE ENERGY parameter. The
energy can be adjusted from 50% to 99% with 1%
step. LED display lights on constantly in idle or
continuous operation modes. It blinks in burst mode,
the duration of LED light on and off states
corresponds to the duty cycle. Please push the control
knob until it clicks and hold it for one second to
switch into triggering TEST mode. HV ON/OFF push
button is blocked in this mode. LED display shows
00
, which means zero output power. Triggering
sequence from the internal or external source goes to
SYNC OUT connector. This mode allows to test the
triggering and see the exact triggering sequence
without applying HV pulses to the load. Please push
the control knob and hold for one second again to
switch back into PULSE ENERGY mode.
If the internal temperature exceeds a safe level, then
OVERHEAT LED lights on, and the generator stops
the operation. It may occur in case of high ambient
temperature / insufficient cooling or after long-time
operation at high amplitude and high repetition rate.
HV ON/OFF button is blocked while the generator is
overheated. Please stay the generator in idle mode, and
allow cooling by the fans for several minutes. The
generator
will
return
to
normal
operation
automatically when the temperature decreases; press
HV ON again to continue the operation.
BNC input connector for external triggering pulses.
The amplitude should be +2.4V … +5V, the nominal
pulse width is 1 µs. External synchronization mode is
activated by pressing INT/EXT green push button.
BNC output connector for SYNC OUT pulses. The
front edge of SYNC OUT pulse precedes HV output
pulse by ~1 µs. SYNC OUT pulse duration is 400 ns,
the amplitude is 3V@50Ω.
